Abstract

We review recent magneto-Raman experiments on electronic excitations in GaAs–AlGaAs quantum wires and dots. We observe simultaneously collective spin-density and charge-density excitations (SDEs and CDEs), and also single-particle-like excitations. In a magnetic field, the CDEs (magnetoplasmons) exhibit a complex anticrossing behavior, which, in quantum wires, strongly depends on the direction of ...
